Thank you very much spindles for your time!
Here some outputs:

I have to say that the sound quality increased a bit since the last time (like magic). The only thing I remember doing is following these instructions:
http://www.linuxquestions.org/questi...highlight=alsa
Namely:
su -c 'vi /etc/pulse/default.pa'
replace load-module module-hal-detect
with load-module module-hal-detect tsched=0
su -c 'yum -y install pavucontrol pavumeter paman padevchooser paprefs alsa-plugins-pulseaudio gstreamer-plugins-pulse pulseaudio pulseaudio-core-libs pulseaudio-esound-compat pulseaudio-libs pulseaudio-libs-glib2 pulseaudio-libs-zeroconf pulseaudio-module-gconf pulseaudio-module-x11 pulseaudio-module-zeroconf pulseaudio-utils xine-lib-pulseaudio xmms-pulse'
pulseaudio -k
Well at least some apps and games work bether. (like vlc)
Sorry for posting this problem before looking at the other thread, but it was just coincidence... The problem is half solved now, but there is still a little bad sound!
Mainly games have problems with sound quality. (for example SuperTux, glest)
Thank you guys!
EDIT: where can I choose which sound system to use? OSS/ALSA?
